PetscSectionCreateGlobalSection
Create a section describing the global field layout using the local section and an SF describing the section point overlap.
Synopsis
#include "petscvec.h"
PetscErrorCode PetscSectionCreateGlobalSection(PetscSection s, PetscSF sf, PetscBool includeConstraints, PetscBool localOffsets, PetscSection *gsection)
Input Parameters
+ s - The PetscSection for the local field layout
. sf - The SF describing parallel layout of the section points (leaves are unowned local points)
. includeConstraints - By default this is PETSC_FALSE, meaning that the global field vector will not possess constrained dofs
- localOffsets - If PETSC_TRUE, use local rather than global offsets for the points
Output Parameter
. gsection - The PetscSection for the global field layout
Note: This gives negative sizes and offsets to points not owned by this process
